Hello. Been awhile since I've posted in the TiVo community but I've bought a Bolt and having trouble with the MoCa network. I'm using a MoCa spliter left behind by the previous Direct TV service I had.The Bolt works well connected HDMI to my main tv. One of my minis also works well. But no link up to my second mini. See attached diagram. I finaly gave in to a ethernet connection to that mini that works but is a bit sluggish compared to the coax connection of the other mini. I've read the postings in here and saw talk of changing MoCa channels. Is that something I need to do?
